These Terms of Service (the “Terms”) set forth the conditions for using the smartphone application “ShutterDNA” (the “App”) provided by Sunabalab Inc. (the “Company”) and the services provided by the Company in connection with the App (collectively, the “Service”).

Users must agree to these Terms before using the Service.

Article 1 (Application)

  2. Descriptions, guidelines, help, notices, the Privacy Policy, and other rules concerning the Service that the Company publishes in the App, on its website, in the App Store or Google Play, or through other media form part of these Terms.
  3. If these Terms conflict with any rules described in the preceding paragraph, these Terms prevail unless the relevant rules expressly provide otherwise.

Article 2 (Definitions)

The following terms have the meanings set out below.

  1. “User” means any individual or legal entity that uses the Service.
  2. “Photo Data” means photo files, image files, video files, and other media files stored on a User's device or within a scope selected by the User.
  3. “EXIF Data” means capture date and time, location data, camera model, lens, focal length, ISO sensitivity, shutter speed, aperture, image dimensions, and other metadata contained in Photo Data.
  4. “Analysis Data” means shooting patterns, profile results, reports, quests, statistics, and other derivative information generated by the App from EXIF Data or other metadata.
  5. “Profile Results” means a “photography personality profile,” “Photography DNA,” “annual report,” or other results generated by the App based on EXIF Data.
  6. “Share Card” means an image, text, card-style report, or similar content generated in the App that a User can share to social media or another external service.

Article 3 (Service Description)

  1. The Service uses EXIF Data and other metadata in a User's Photo Data to display shooting patterns, preferred shooting times and places, camera and lens usage, photography personality profiles, annual reports, photography quests, and similar information.
  2. As a general rule, the Service does not analyze people, faces, objects, scenery, text, food, place content, or any other image content shown in photos.
  3. The Service does not provide medical or psychological diagnoses, personality assessments, credit decisions, employment decisions, insurance decisions, security decisions, legal judgments, or other professional determinations.
  4. Profile Results, reports, quests, comments, scores, and other displays are reference information intended to help Users enjoy reflecting on their shooting habits. Their accuracy, completeness, usefulness, or fitness for a particular purpose is not guaranteed.
  5. Some Service features may be unavailable depending on the device, operating system, permission settings, type of Photo Data, availability of EXIF Data, cloud-photo status, App version, or other conditions.

Article 4 (Handling of Photo Data and EXIF Data)

  1. The App may read EXIF Data and other metadata contained in Photo Data within the scope authorized by the User.
  2. Under the current specifications, the App does not analyze image content or perform face recognition, object recognition, person identification, text recognition, or any other AI image analysis.
  3. Under the current specifications, the App does not upload a User's photo images to Company servers.
  4. EXIF Data and Analysis Data are primarily processed and stored on the User's device.
  5. Users may limit or revoke access to their photo library through their operating-system settings or settings within the App.
  6. If a User does not allow photo-library access or allows access only to selected photos, some Service features may be limited. The Company may nevertheless provide demo data or limited functionality where possible.
  7. If Photo Data includes location data, the App may use it to display shooting patterns, the Memory Gravity Map, and similar features. As a general design principle, however, Share Cards do not display precise addresses, coordinates, place names, or other information that could identify a User's specific location.
  8. Even when location data is used, the App is not intended to continuously track the User's current location.

Article 5 (Granting and Withdrawing Permissions)

  1. Use of the Service may require permissions relating to a photo library, media library, photo-selection function, photo metadata containing location data, or similar resources.

  4. Users view, save, share, and use Profile Results at their own responsibility.
  5. The Company is not liable for damage arising from Profile Results or a User's use of them, except in cases of willful misconduct or gross negligence by the Company. Where the Company's liability is restricted under the Consumer Contract Act or other applicable laws, those laws apply.

Article 7 (Share Cards and Sharing to External Services)

  1. Users may share Share Cards, Profile Results, reports, text, and other App-generated content to social media, messaging apps, email, and other external services.
  2. Users must review what they share and share it at their own responsibility.
  3. The Company endeavors to design Share Cards so that they do not include precise addresses, coordinates, file names, individual photo images, face information, object-recognition results, or other sensitive information. The Company is not responsible, however, for information a User adds through screenshots, annotations, edits made on an external service, or other means.
  4. Information shared to an external service is governed by that service's terms, privacy policy, and other conditions.
